Indents in Taskpaper modebrowsing

I use Sublime Text 2 on my Mac to edit .taskpaper files and on iOS I use Editorial. I've set Sublime to use tabs for indents. With any indented (below a project) tasks I create with Sublime, they appear normally in Editorial, but when I tap the checkbox, the @done tag gets added with a timestamp, but the checkbox doesn't get checked and strikethrough doesn't show. For tasks I create in Editorial everything works as expected, it's just with the tasks created in Sublime that this happens.
